• Integrated Safety Cut‑Off: A built‑in limit switch prevents over‑extension of the window, protecting both the glass and the regulator mechanism.
• Low‑Noise Operation: Advanced bearing design and motor shielding reduce audible noise, ensuring a quiet cabin environment.
• Corrosion‑Resistant Housing: The regulator’s aluminum housing is anodized and coated to resist rust, corrosion, and UV degradation.
• Modular Wiring Harness: The AC361 includes a pre‑wired harness compatible with standard automotive electrical systems, simplifying installation.

Technical Specifications

Installation Overview

The AC361 is designed for straightforward installation in front passenger side windows. The process typically involves the following steps:

1. Remove Existing Regulator: Detach the current window winder by unscrewing the mounting bolts and disconnecting the wiring harness.
2. Prepare Mounting Surface: Clean and level the mounting area to ensure a secure fit.
3. Attach AC361: Align the regulator with the mounting holes and secure it using the supplied bolts.
4. Connect Wiring Harness: Plug the pre‑wired harness into the vehicle’s electrical connector, ensuring correct polarity.
5. Test Operation: Verify that the window moves smoothly in both directions and that the limit switches engage properly.
6. Seal and Finish: Apply weather‑proof sealant around the regulator to prevent water ingress.

Maintenance Tips

• Regular Inspection: Check for loose bolts or worn seals every six months.
• Lubrication: Apply a light silicone lubricant to the regulator’s pivot points annually to maintain smooth motion.
• Electrical Check: Inspect the wiring harness for fraying or corrosion; replace any damaged sections immediately.
• Cleaning: Wipe down the regulator housing with a mild detergent to remove dust and grime.

Compatibility Highlights

The AC361 is engineered to fit a wide range of compact and sub‑compact vehicles, particularly those featuring the Smart Fortwo, City, and similar models. Its modular design allows for easy adaptation to various front passenger side window configurations, ensuring a seamless fit across multiple platforms.

Performance Benefits

• Enhanced Reliability: The brushless motor reduces wear and extends the lifespan compared to brushed counterparts.
• Energy Efficiency: Low idle current and efficient motor design minimize battery drain.
• Quiet Operation: Reduced mechanical noise contributes to a more comfortable driving experience.
• Safety Assurance: Built‑in limit switches prevent accidental over‑extension, protecting both occupants and the vehicle structure.
